Cardiovascular Exercise: Article Analysis

Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently.

There are many benefits of having a good cardiovascular endurance. The first one is an improved condition of your heart. Just like any other muscle in order for heart to become strong it must be worked. if you fail to work it, it will weaken over time and can cause a variety of health problems. By having a good cardiovascular endurance the heart is pumped at a faster rate and will keep it in a healthier shape. Cardio training can also help maintain weight and can also decrease the chances of type 2 diabetes. Aerobic exercises have not only have health benefits it also have some social benefits it could make you feel better, improve self-esteem and you will be able to play sports or exercises with your friends for a longer period of time

A person's cardiovascular system is a very important part of fitness and one's overall health. Here are a few of the best exercises; walking running, cycling, rowing, swimming. Research suggests at least 150 minutes per week, a minimum of 30 minutes per day, five times a day a week. A few exercises that are best are, climbing, playing sports, and running is also some of the most common and affordable. At least 25 minutes of vigorous aerobic activity at least or a combination of moderate and aerobic activity are some of the best options to benefit your cardiovascular system.

Introduction: Exercise is a physical activity or particular movement that is used in order to become healthier and stronger. (1) Exercise, in all of its forms, has various effects on the different systems in the human body. One of the main benefits is cardiovascular health, including circulation and heart health. Exercise uses a lot of energy, which the cells derive from oxidising glucose. Meaning that the heart has to work harder to pump more blood throughout the body and the heart has to beat faster in order to achieve a high effort. (2) The heart benefits from exercise include being able to pump more blood through the body and continue working at a higher level with less strain. (3)

Hello Dr. Hultgren! Thank you for pointing out that my research question represents a longitudinal study. I mentioned in my initial post that a mixed methods research would be better, but I only presented a quantitative question. You made great suggestions of what to consider when asking a qualitative question for this particular study. Perhaps a sound qualitative question to inquire is: In adults 18 years and older who are consuming polyphenols, does ingestion of various types of these compounds give them better energy and performance levels compared to just consuming one particular polyphenol-rich dietary source (for example grapes over cocoa) right after ingesting it? Thank you

Exercising stimulates Vasodilation and Vasoconstriction to facilitate the oxygen delivered to the muscles. It also keeps the blood vessels healthy and stops the accumulation of cholesterol and harmful substances. It can also help on warming up and cooling down of the

Obesity rates have continued to raise over the years. In America 1 out of 3 adults were considered to be obese. Due to these statistics obesity has become a huge concern for our country. Factors that are related to obesity are heart diseases, health issues, diabetes, and hypertension. To not be another statistic we must have a healthy nutrition and have physical activities in our daily routines. Aerobics is a great way to start a healthy lifestyle. As said in myDr, "Regular aerobic exercise improves your cardiovascular fitness by increasing your capacity to use oxygen. It does this by increasing your heart’s capacity to send blood (and hence oxygen) to the muscles." Cardiovascular exercise is extremely important because reduces health problems, improved bone and muscle health, and controls your weight.

In the article Exercise: 15 minutes a day ups lifespan by 3 years, research done by the Harvard Heart Letter proved that at the minimum 15 minutes of daily exercise would reduce inflammation levels that can affect heart health and will improve the body’s ability to fight against oxidants that damage the cells in the body. Their research also has proved that it is most beneficial for a person to include a combination aerobic exercise, strength training, and stretching in their daily exercise routine. Low intensity aerobic exercise such as walking is the best type of exercise to increase cardiovascular health and allow for a decrease in the inflammation of

Exercise is another key to maintain a healthy heart and cardiovascular system. The American Heart Association recommends 150-minutes of moderate-intensity, aerobic, physical activity, or 75-minutes of vigorous-intensity, aerobic, physical activity. To stave off boredom, it’s suggested to do a combination of both types of exercise throughout the week (American Heart Association, 2017). Aerobic physical activity is described as, “Exercise with oxygen.” During this type of exercise, the body, more specifically the heart, is working hard to pump oxygenated blood from the heart to the muscles throughout your body (another name for this type of exercise is cardio-exercise). Specific examples of aerobic exercise are; cardio machines, walking, jogging, running, swimming, hiking, and even dancing. The intensity of the exercise depends on how fast and how long the exercise is consistently maintained over a period of time (Weil, n.d.).

2a &b. Aerobic exercise helps the body use insulin better and strengthen the heart and bones, improves blood circulation, relieves stress, reduces the risk for heart disease by lowering blood glucose and blood pressure as well as improve the cholesterol levels.

4) following an active lifestyle improves cardiovascular endurance by increasing the body’s efficiency for using oxygen which allows the heart to perform more works with less beats. It also increases lean body weight which leads to an increase in the metabolic rate and this helps in weight control. Being physically active reduces stress by producing norepinephrine, it will also help you to feel calmer and relax by releasing endorphins which will help to cope stress.

Exercise is generally thought of as being one of the most practical and effective ways for the average person to lower their risk of heart disease. Physical activity lowers blood pressure and helps keep vessels in preferable condition. Dying from cardiovascular disease is more than twice as likely in the obese.

This allows your cardiovascular centres in your brain a little bit more latitude as far as controlling your heart rate. If you were to remove a beating heart from someone's body you would find that the heart is no longer being suppressed by the parasympathetic nervous system and it will accelerate to the same pace as the sinoatrial node. The SA node generates action potentials approximately 100 times per minute due to the physiology of the heart, its own permeability to sodium and calcium via its channels, and a host of other things. Anywhere between 80 to 100 beats per minute is normal for the SA node.

INTRODUCTION: High-Intensity Interval Training (HIIT) is known as one method to treat Cardiovascular Diseases (CD), such as Coronary Arterial Disease (CAD) and Heart Failure (HF), due to its potential to improve cardio respiratory fitness (1, 15). This exercise format is characterized as aerobic exercise performed in a high intensity - usually controlled by either maximum oxygen uptake or maximum heart rate – with active and low intensity. Performing exercise in high intensities mixed with active rest allows patients to tolerate a higher effort before they become tired. Heart failure patients present a diminished exercise capacity, due to a smaller Ejection Fraction (EF), which tells us how well the heart pumps blood to body. To these patients, High-Intensity Interval Training has been reported for improving Systolic Function due to the increased effort in which the heart is working (16). The necessity to provide nutrients through circulation during exercise leads to an increased contractility and consequently LV Remodeling (15). Coronary Arterial Disease Patients have a decreased blood flow to the myocardial tissue due to an obstruction inside the coronary arteries. HIIT increases the arteriovenous O2 difference, which means there is an elevated consumption of oxygen by the tissues as result of a higher stroke volume. All those benefits have been shown in the literature, but most of the studies present data with short-term interventions. A few studies discuss the benefits

The muscles demand more energy and oxygen due to the increased workload that comes from exercise. This causes the heart rate and respiratory rate to increase in order to provide the required additional fuel to the muscles. In addition, the entire circulatory system works more efficiently due to vascular dilation and cholesterol reduction. By improving the condition of your cardiovascular fitness you are also helping yourself live longer, decrease the risk of heart disease, lower blood pressure, strengthen your cardiovascular system, and the list goes on. These reasons alone could save you from having heart disease.
